Description

  The present invention relates to a sheet-like hair cosmetic, a hair treatment method using the same, and a scalp wiping method.

Sebum, sweat, and odors attached to the scalp and hair in situations where the water cannot be fully used, such as when going out, during long-term hospitalization, elderly in nursing homes, leisure activities such as mountain climbing or camping, or when water has stopped due to a disaster. There is a demand to remove dirt and to prepare a hairstyle.
In addition, when preparing hair into a natural shape, it is common to apply water or a hair styling agent to the hair and let it dry naturally, or use a heating tool such as a dryer. There are restrictions on using not only hairdressing agents but also water, and it is extremely difficult to meet the above-mentioned demands for cleanliness or keeping a beautiful hairstyle.

The main function of shampoo is to remove dirt, etc. from hair, and shampoo liquid and dirt are generally washed away with water, but in order to remove dirt on hair and scalp in situations where water cannot be used. As such, a so-called dry shampoo sheet is known. For example, in Patent Document 1, a dry substrate in which a non-woven support having an area of 500 to 900 cm ² and a thickness of 0.1 to 3 mm is impregnated with a composition containing water, ethanol and l-menthol. A shampoo sheet is described. Patent Document 2 describes a dry shampoo sheet obtained by impregnating a liquid agent into a 450 to 550 cm ² non-woven fabric containing rayon and a heat-sealing resin. This liquid agent contains ethanol, a humectant, a surfactant, and water. Moreover, the dry shampoo sheet described in the document is intended to be used in combination with a tool having a large number of convex portions on the surface.

  On the other hand, a skin-cleaning sheet cosmetic for removing dirt on the skin surface is well known. For example, in Patent Document 3, a sheet having a thickness of 0.1 to 0.3 mm and a bending hardness in the vertical and horizontal directions of 1.0 to 10.0 mN · cm measured according to the cantilever method. A skin-cleaning sheet-like cosmetic comprising a base material impregnated with an aqueous medium is disclosed. This skin-cleansing sheet-like cosmetic is intended to remove sebum and dirt on the skin surface. In this skin cleansing sheet-like cosmetic, a thin and hard sheet base material is used for the purpose of preventing the sheet base material from being bent during use and enhancing the usability.

  However, since the dry shampoo sheets described in Patent Documents 1 and 2 are mainly intended to remove dirt on the hair and / or the scalp, they are not sufficient in terms of hair care on the go. For example, from the viewpoint of hair care, such as when you want to reduce hair splashes and floats, and to give hair a unit again or give a treatment effect when you can't use plenty of water, Where it is necessary to impregnate the entire hair with a sufficient amount of the liquid agent, this is not necessarily sufficient from the viewpoint of impregnating the entire hair with a sufficient amount of the liquid agent while maintaining portability.

Moreover, although the hair has an outer surface and an inner surface with respect to the body surface, the dry shampoo sheets described in Patent Documents 1 and 2 both apply the liquid agent from the root of the hair to the end of the hair. In some cases, a sufficient solution cannot be applied to the hair located on the inner surface. Furthermore, when this dry shampoo sheet is used by hand in the state where there are not enough tools such as brushes, it may be difficult to use the liquid agent evenly over the entire hair.
In addition, when the sheet is fixed to a tool such as a brush and applied to the hair, for example, it is easy to remove the dirt attached to the hair on the outer side of the hair, but it is on the inner side of the hair or the back of the overlapping hair It was difficult to remove hair stains, and it was very difficult to evenly apply a sufficient solution.

  In addition, when the scalp is wiped, unlike the face and body, the hair grows densely on the scalp, so that it becomes an obstacle when the scalp is wiped. For this reason, the sheet-like cosmetic for skin as described in Patent Document 3 is insufficient for wiping the scalp. Further, unlike the face and body, hair is a dry protein with a low water content and has a very large surface area. Therefore, in the sheet-like cosmetic for skin as described in Patent Document 3, the hair is applied to the fingers of the sheet. Insufficient follow-up and insufficient amount of impregnating liquid, a sufficient wiping effect and treatment effect could not be obtained.

  Therefore, the subject of this invention is providing the sheet-like hair cosmetics which can eliminate the fault which the prior art mentioned above has.

  As a result of intensive studies by the present inventors to solve the above-mentioned problems, in treating and wiping hair, it is easy to spread the sheet-like hair cosmetic when it is taken out from the outer container, and follow the fingers of the sheet-like hair cosmetic. It is important that the sheet be impregnated with and hold a liquid cosmetic composition in an amount suitable for hair treatment, and that the sheet strength is sufficient against physical forces such as friction. As a result, the present invention was completed.

  The present invention will be described below based on preferred embodiments with reference to the drawings. FIG. 1 is a perspective view in which one embodiment of a hair cosmetic product in which a sheet-like hair cosmetic product according to an embodiment of the present invention is housed in an exterior container is partially broken. The hair cosmetic product 10 shown in the figure has an exterior container 11. The exterior container 11 is formed, for example, by processing one sheet material. Specifically, a pair of opposing sides in one sheet material are joined so as to overlap each other (not shown), the sheet material is formed into a cylindrical shape, and 2 in the cylindrical sheet material. The two openings are respectively sealed by the heat seal part 11a or the like. In the following description, the hair cosmetic product 10 in which the sheet-like hair cosmetic product of the present embodiment is housed in an exterior container is also simply referred to as “the hair cosmetic product 10 of the present embodiment”.

  As the sheet material constituting the outer container 11, for example, a water-impermeable material can be used within a range that is normally used. In addition to being impervious to water, the sheet material is preferably impermeable to water vapor and ethanol volatilized from the sheet-like hair cosmetic. By using the sheet material having such properties, it is possible to effectively exude and volatilize the liquid cosmetic composition from the wet sheet-like hair cosmetic 13 accommodated in the exterior container 11. Can be prevented. Examples of the sheet material having such properties include a thermoplastic resin film in which aluminum is vapor-deposited, a film in which aluminum is sandwiched between thermoplastic resin films, and the like.

  The exterior container 11 has the upper surface 11b and the lower surface (not shown) facing this. Moreover, the exterior container 11 also has the 1st side surface 11c and the 2nd side surface (not shown) facing this. A content outlet 11d is formed at a substantially central position of the upper surface 11b. The content outlet 11d can have a long hole shape extending in the same direction as the longitudinal direction of the upper surface 11b, for example, but is not limited to this shape. The wet sheet 12 accommodated in the outer container 11 is taken out through the content outlet 11d. The shape of the content outlet 11d is not particularly limited. From the viewpoint that the sheet-like hair cosmetic 13 is easily expanded when the sheet-like hair cosmetic 13 is taken out through the content outlet 11d, the content outlet 11d is used. 11d is preferably in the shape of, for example, a rectangle, an ellipse, a square or a square, or a circle or a circle.

Since the wet sheet-like hair cosmetic 13 taken out from the outer container 11 is impregnated with a large amount of the liquid cosmetic composition as will be described later, the sheet-like hair cosmetics 13 tend to stick to each other and hardly spread. However, from the viewpoint of easily spreading the sheet-shaped hair cosmetic product 13, it is preferable that the opening area of the content outlet 11d is not excessively large. Specifically, the area of the content outlet 11d is advantageously set to 4000 mm ² or less, preferably 3000 mm ² or less, more preferably 2500 mm ² or less. On the other hand, from the viewpoint of taking out from the outer container 11 while sufficiently impregnating the liquid cosmetic composition impregnated into the sheet-like hair cosmetic 13, it is preferable that the opening area of the content outlet 11d is not excessively small. Specifically, the area of the content outlet 11d is advantageously set to 25 mm ² or more, preferably 100 mm ² or more, and more preferably 200 mm ² or more. For example, preferably contents outlet 11d is the area is 25 mm ² or more 4000 mm ² or less, further preferably 100 mm ² or more 3000 mm ² or less, and still more preferably 200 mm ² or more 2500 mm ² or less.

  The position of the content outlet 11d is such that the folding line in the sheet-shaped hair cosmetic 13 that is folded and stored from the viewpoint of facilitating the spreading of the wet sheet-shaped hair cosmetic 13 taken out from the outer container 11 is the content. It is preferable that the sheet-like hair cosmetic 13 is folded and accommodated in the exterior container 11 so as to be disposed at a position visible from the outlet 11d. From the same viewpoint, regardless of whether or not the sheet 12 is folded, the sheet-like hair cosmetic 13 is disposed such that the end of the sheet-like hair cosmetic 13 is visible from the content outlet 11d. It is preferable to be accommodated in the outer container 11.

  An open / close lid 11e is disposed on the upper surface 11b of the outer container 11 so as to cover the entire area of the content outlet 11d. The opening / closing lid may be anything as long as it can seal the contents such as water vapor and ethanol volatilized from the sheet-like hair cosmetic, and examples include an opening / closing lid having a hinge, a sheet-like shape, and a valve-like shape. In the present embodiment, the opening / closing lid 11e is in the form of a sheet, and an adhesive (not shown) is applied to the surface facing the upper surface 11b, and the adhesive opens and closes the upper surface 11b of the outer container 11 with the adhesive. The lid 11e can be peeled, and the peeled peeled portion can be reattached so as to cover the content outlet 11d. As the adhesive that can be re-adhered, pressure-sensitive adhesives that are conventionally used in the technical field, such as polyester-based, acrylic-based, rubber-based, and the like can be used. During storage of the hair cosmetic product 10 of the present embodiment, the opening / closing lid 11e covers the entire area of the content outlet 11d, and part or all of the opening / closing lid 11e is peeled off from the upper surface of the outer container 11 during use. The content outlet 11 is exposed. Then, the wet sheet-like hair cosmetic 13 accommodated in the outer container 11 is picked with a finger and taken out through the content outlet 11.

  In the outer container 11, a wet sheet-like hair cosmetic product 13 impregnated with a liquid cosmetic composition is accommodated. The sheet-like hair cosmetic product 13 is accommodated by laminating a plurality of sheets in a state of being folded into a predetermined shape or not being folded. From the viewpoint of improving the portability of the hair cosmetic product 10, it is advantageous that the sheet-like hair cosmetic product 13 is folded and accommodated. In the following description, the term “sheet” refers to a wet state impregnated with a liquid cosmetic composition or a dry state not impregnated with a liquid cosmetic composition depending on the context. . Since the sheet-like hair cosmetic product 13 impregnated with the liquid cosmetic composition is accommodated in the outer container 11, the portability of the hair cosmetic product 10 of the present embodiment is remarkably increased, and in various situations such as where to go. The convenience will be good.

Whether the sheet-like hair cosmetic 13 is folded in terms of the area of the sheet-like hair cosmetic 13 in the state of being accommodated in the outer container 11 in relation to the opening area of the content outlet of the outer container 11 Regardless of whether or not, it is preferably 10 cm ² or more, preferably 400 cm ² or less, more preferably 300 cm ² or less, and even more preferably 200 cm ² or less. For example, the area of the sheet-like hair cosmetic product 13 in a state of being accommodated in the outer container 11 is preferably 10 cm ² or more and 400 cm ² or less, more preferably 10 cm ² or more and 300 cm ² or less, it is more preferably 10 cm ² or more 200 cm ² or less.

  The sheet 12 may be a single layer sheet or a sheet having a multilayer structure of two or more layers. Further, it may be a multi-ply sheet in which a plurality of non-woven fabrics are laminated. Furthermore, a film (so-called back sheet) that does not penetrate the liquid cosmetic composition may be attached to one surface of the sheet. Although the sheet | seat 12 is generally a rectangular thing, you may employ | adopt shapes other than a rectangle from a viewpoint of performing the wiping operation of hair and a scalp more smoothly.

  The sheet 12 is preferably a flexible one having high drape properties. Due to being flexible, when the sheet-like hair cosmetic 13 is taken out from the outer container 11 and placed on the palm, the sheet-like hair cosmetic 13 becomes familiar with the fingers and the operability is improved, and the impregnated liquid cosmetic composition Is easily applied to the hair thinly and uniformly. In addition, from the viewpoint of ease of spreading the sheet-shaped hair cosmetic product 13, an appropriate rigidity is required. From these viewpoints, when the flexibility of the sheet 12 before impregnation with the liquid cosmetic composition is represented by the bending resistance measured by the method A (45 ° cantilever method) according to JIS L1096: 2010, This value needs to be 10 mm or more. Moreover, it is preferable that it is 30 mm or more. Moreover, it is advantageous that it is 70 mm or less, 65 mm or less, 60 mm or less, and also 50 mm or less. Specifically, the bending resistance is preferably 10 mm to 70 mm, more preferably 10 mm to 65 mm, and still more preferably 10 mm to 60 mm. It is advantageous that the bending resistance is in the above-mentioned range from the viewpoint of making it easy to take out and spread the sheet 12 from the exterior container 11. The value of the bending resistance of the sheet 12 is calculated as an arithmetic average value of bending resistance in the flow direction (MD) and the width direction (CD).

  As the sheet | seat 12, the fiber sheet which uses fiber materials, such as a nonwoven fabric sheet, for example can be used. In order for the sheet 12 before impregnation with the liquid cosmetic composition to achieve the bending resistance in the above-described range, for example, the type of fibers constituting the sheet 12, the manufacturing method of the sheet 12, the shape of the sheet, and the like are appropriately set. Just choose. With regard to the fiber type, the sheet 12 advantageously contains cellulosic fibers. By using this fiber as a constituent fiber, the sheet 12 has good impregnation retention of the liquid cosmetic composition. Furthermore, the sheet 12 is made suitable when the softness and draping property of the sheet is made appropriate, and the hair and scalp are wiped with the sheet-like cosmetic 12 impregnated with the liquid cosmetic composition. The sheet 12 preferably contains cellulosic fibers and thermoplastic resin fibers from the standpoint that fuzzing and tearing are less likely to occur.

  Cellulosic fibers used as the constituent fibers of the sheet 12 are mainly used to impart impregnation retention of the liquid cosmetic composition to the sheet 12. As cellulosic fibers, for example, hydrophilic fibers such as natural fibers and regenerated fibers can be used. Examples of natural cellulosic fibers include cotton and pulp. Examples of the regenerated cellulose fiber include rayon, cupra, lyocell, and tencel. These cellulosic fibers can be used singly or in combination of two or more.

  The thermoplastic resin fibers used as the constituent fibers of the sheet 12 are mainly used for imparting appropriate wear resistance to the sheet 12. Examples of the thermoplastic resin constituting the thermoplastic resin fiber include polyolefin resins such as polyethylene and polypropylene, polyester fibers such as polyethylene terephthalate, acrylic resins, and polyamide resins. These resins can be used singly or in combination of two or more. The fibers made of these thermoplastic resins may have a single composition consisting of only one kind of resin, or may be made of a blend of two or more kinds of resins. Moreover, the core-sheath-type composite fiber comprised from 2 or more types of resin and the side-by-side type composite fiber may be sufficient. Among them, as the thermoplastic resin fiber, it is preferable to use a polyolefin-based resin such as polyethylene or polypropylene, or a polyester-based fiber such as polyethylene terephthalate from the viewpoint of the bending resistance and mechanical strength of the sheet 12.

  When the sheet 12 contains cellulosic fibers and thermoplastic resin fibers, the ratio of the cellulosic fibers to the thermoplastic resin fibers in the sheet 12 is such that the bending resistance and mechanical strength of the sheet 12 and the sheet 12 are liquid makeup. It can be determined in consideration of the degree of impregnation and retention of the material composition. For example, based on the mass of the sheet 12 before impregnation with the liquid cosmetic composition, the content of the cellulosic fibers is preferably 30% by mass or more, more preferably 35% by mass or more, and more preferably 40% by mass or more. Furthermore, it is still more preferable that it is 50 mass% or more. Further, the content of the cellulosic fibers is preferably 99% by mass or less, more preferably 97% by mass or less, and still more preferably 95% by mass or less. On the other hand, based on the mass of the sheet 12 before impregnation with the liquid cosmetic composition, the content of the thermoplastic resin fibers is preferably 1% by mass or more, more preferably 3% by mass or more, and more preferably 5% by mass. % Or more, more preferably 25% by mass or more. Further, the content of the thermoplastic resin fiber is preferably 70% by mass or less, more preferably 65% by mass or less, further preferably 60% by mass or less, and further preferably 50% by mass or less. . Specifically, based on the mass of the sheet 12 before impregnation with the liquid cosmetic composition, the proportion of the cellulosic fibers is preferably 30% by mass or more and 99% by mass or less, and 35% by mass or more and 97% by mass or less. More preferably, it is 40 mass% or more and 95 mass% or less, More preferably, it is 50 mass% or more and 95 mass% or less. On the other hand, the thermoplastic resin fiber is preferably 1% by mass or more and 70% by mass or less, more preferably 3% by mass or more and 65% by mass or less, and further preferably 5% by mass or more and 60% by mass or less. More preferably, it is more preferably 25% by mass or more and 50% by mass or less.

  In order to control the bending resistance of the sheet 12 from the viewpoint of the manufacturing method of the sheet 12, it is advantageous to employ a manufacturing method of a method in which the intersections of the constituent fibers are not coupled as the manufacturing method of the sheet 12. As such a production method, for example, a nonwoven fabric production method such as a spunlace method or a needle punch method can be employed. Furthermore, since the sheet 12 having low bending resistance and high drapeability can be obtained, it is preferable to employ a spunlace method as a nonwoven fabric manufacturing method. When the sheet 12 is manufactured by the spunlace method, the sheet 12 is maintained in a non-woven fabric form only by entanglement of its constituent fibers. In some cases, instead of maintaining the form of the nonwoven fabric only by entanglement of the constituent fibers, in addition to the entanglement of the constituent fibers, some of the intersections of the constituent fibers may be bonded by thermal fusion or adhesive bonding. Good.

  When the sheet 12 is manufactured by the spunlace method, a web made of the constituent fibers of the sheet 12 may be formed and fluid may be sprayed onto the web. As the fluid, liquid is preferably used, but in some cases, gas may be used. As the fluid, it is advantageous to use water because it is easy to handle. In the spunlace method, the degree of fiber entanglement can be adjusted by adjusting the pressure or the like when the fluid is sprayed on the web, and thereby the bending resistance of the sheet 12 can be adjusted.

From the viewpoint of impregnating the liquid cosmetic composition in an amount that can sufficiently wipe both the hair and scalp, and from the viewpoint of smoothly performing the wiping operation of the hair and scalp, the sheet 12 has an apparent area of 50 cm ² or more. Further, it is preferably 100 cm ² or more, more preferably 200 cm ² or more. From the same viewpoint, the sheet 12 preferably has an apparent area of 1600 cm ² or less, more preferably 900 cm ² or less, and further 700 cm ² or less. Specifically, the sheet 12 is preferably the apparent area is 50 cm ² or more 1600 cm ² or less, still more preferably 100 cm ² or more 900 cm ² or less, and still more preferably 200 cm ² or more 700 cm ² or less. The apparent area is an area of a region defined by the outline in a state where the sheet 12 is spread flat and viewed in plan. Therefore, even if the sheet 12 has irregularities and openings, they do not affect the apparent area.

  The mass of the sheet 12 before impregnating the liquid cosmetic composition also affects the amount of impregnation of the liquid cosmetic composition and the wiping operation of hair and scalp. From this viewpoint, the sheet 12 before impregnation with the liquid cosmetic composition preferably has a mass of 0.5 g or more, further 1.0 g or more, and further 1.5 g or more. Further, it is preferably 8.0 g or less, more preferably 6.0 g or less, and further preferably 4.0 g or less. Specifically, the sheet 12 before impregnation with the liquid cosmetic composition preferably has a mass of 0.5 g or more and 8.0 g or less, and preferably 1.0 g or more and 6.0 g or less. More preferably, it is 0.5 g or more and 4.0 g or less.

In relation to the mass of the sheet 12, the sheet 12 before impregnated with the liquid cosmetic composition imparts a bending resistance to the sheet 12 and gives a bending resistance suitable for improving the operability of the hair treatment with a hand comb. From the viewpoint of sufficiently impregnating and retaining the liquid cosmetic composition, the basis weight is 10 g / m ² or more, further 15 g / m ² or more, further 20 g / m ² or more, and further 25 g / m ² or more. preferable. From the same viewpoint, it is preferably 200 g / m ² or less, more preferably 150 g / m ² or less, further 100 g / m ² or less, and further 80 g / m ² or less. Specifically, the sheet 12 before impregnation with the liquid cosmetic composition preferably has a basis weight of 10 g / m ² or more and 200 g / m ² or less, and 15 g / m ² or more and 150 g / m ² or less. More preferably, it is more preferably 20 g / m ² or more and 100 g / m ² or less.

  The thickness of the sheet 12 before impregnation with the liquid cosmetic composition is preferably thin from the viewpoint of portability, and is preferably thick from the viewpoint of impregnation retention of the liquid cosmetic composition. Moreover, it is preferable that it is thick also from a viewpoint of abrasion resistance. In consideration of these balances, the thickness of the sheet 12 before impregnation with the liquid cosmetic composition is preferably more than 0.3 mm, more preferably 0.4 mm or more, and 0.5 mm or more. More preferably, it is 0.7 mm or more, still more preferably 0.8 mm or more. From the same viewpoint, it is preferably 5 mm or less, more preferably 4 mm or less, preferably 3 mm or less, and further preferably 1.3 mm or less. Specifically, the thickness of the sheet 12 before impregnation with the liquid cosmetic composition is preferably more than 0.3 mm and not more than 5 mm, more preferably not less than 0.4 mm and not more than 4 mm. More preferably, it is 5 mm or more and 3 mm or less, and more preferably 0.7 mm or more and 3 mm or less. The thickness of the sheet 12 is measured in accordance with “Thickness measurement of fabric and fiber product” described in JIS L 1096: 2010, for example, using Daiei Kagaku Seiki Seisakusho Co., Ltd. (model FS-60DS), Measured under a load of 0.3 kPa.

  From the viewpoint of controlling the bending resistance of the sheet 12 and the impregnation retention of the liquid cosmetic composition, a concavo-convex structure may be formed on one surface or both surfaces of the sheet 12. Alternatively, an opening may be provided in the sheet 12.

  When the uneven structure is formed on the surface of the sheet 12, there is an advantage that physical irritation to the hair or scalp is reduced when the hair is wiped due to the cushioning property due to the uneven structure. Further, there is an advantage that the sheet 12 is easily bent due to the concavo-convex structure, and becomes more familiar with the hand when the sheet 12 is placed on the hand so as to be applied to the finger. When forming a concavo-convex structure on the surface of the sheet 12, the convex portions and the concave portions may be dispersedly arranged in the form of dots, or in multiple rows so as to extend in a specific direction along the plane of the sheet 12. It may be formed. From the viewpoint of uniformly applying the liquid cosmetic composition to the hair and further improving the unity of the hair, the concavo-convex structure extends in one direction along the plane of the sheet 12 and is formed in multiple rows. It is preferable. The reason for this is that when the hair is treated or wiped with a hand comb using a sheet-like hair cosmetic, the contact area between the hair and the sheet-like hair cosmetic is increased by the hair being caught in a recess extending in one direction, It is expected that the liquid cosmetic composition is applied more uniformly. Moreover, when the uneven | corrugated structure is formed in both surfaces of the sheet | seat 12, the other surface corresponding to the position in which the convex part is formed in one surface may be a recessed part, or it is a convex part. Also good. Similarly, the other surface corresponding to the position where the concave portion is formed on one surface may be a convex portion, or may be a concave portion.

  Moreover, when the uneven | corrugated structure is formed in both surfaces of the sheet | seat 12, the sheet | seat 12 is planarized from a viewpoint which controls the discharge | release property of a liquid cosmetic composition and apply | coats a liquid cosmetic composition thinly and uniformly with respect to hair. When viewed, it is preferable that the position where the convex portion is formed on one surface substantially coincides with the position where the convex portion is formed on the other surface. By using the sheet 12 having such a concavo-convex structure, when the liquid cosmetic composition is thinly and uniformly applied to the hair, it can give the hair a natural feeling of unity, and also the hair and floating hairs It becomes easy to prepare.

Furthermore, when the uneven structure is formed on both surfaces of the sheet 12, the thickness of the sheet is controlled from the viewpoint of controlling the release of the liquid cosmetic composition and applying the liquid cosmetic composition thinly and uniformly to the hair. Is preferably not uniform. Specifically, for example, as shown in FIG. 3, the height difference D _a and D _b from the top of the convex portion to the bottom of the concave portion is measured on both surfaces of the sheet 12, and the surface having the larger height difference is defined as the first surface. Sometimes, the sheet thickness of the convex portion on the first surface is preferably larger than the sheet thickness of the concave portion on the first surface. The sheet thickness of the convex part and the sheet thickness of the concave part are the thicknesses at the part where the fiber actually exists. Here, when measuring the thickness of the sheet, it is obtained by cutting the sheet with a razor and observing the cross section with a microscope.

  When forming a convex part and a recessed part in the sheet | seat 12, it is preferable from a viewpoint of the impregnation retainability of a liquid cosmetic composition, and the discharge | release property of a liquid cosmetic composition that a convex part and a recessed part differ. Specifically, when comparing the basis weight of the convex portion and the concave portion, the basis weight of the convex portion is higher than the basic weight of the concave portion, and holds a large amount of liquid cosmetic composition, It is preferable at the point which becomes easy to discharge | release by the pressing pressure when wiping. Regarding the basis weight, it is preferable from the same viewpoint that the basis weight of the convex portion is higher than the basis weight of the concave portion.

  In addition, when calculating the basic weight of a convex part and a recessed part, a convex part and a recessed part are cut out from a sheet | seat, each mass and area of a convex part and a recessed part are measured, and it calculates by dividing a mass by an area. The basis weight of the convex part and the concave part may be calculated after measuring the area using an image analysis system described later, or may be calculated using the method described below. Here, when an opening is provided in the recess, the basis weight of the recess is calculated using the area of the recess excluding the area of the opening. On the other hand, when calculating the basic weight of the whole sheet | seat 12, it calculates from the area (namely, apparent area) of the whole sheet | seat including the area of an opening.

[Calculation method of basis weight of convex part and concave part]
(1) A sheet is cut into a size of 10 cm × 10 cm.
(2) The cut sheet is cut into a convex portion and a concave portion, and the total mass (g) of the convex portion and the total mass (g) of the concave portion are each weighed precisely to 0.1 mg.
(3) A square mount having a size of 10 cm × 10 cm is prepared and used as an area standard paper. All sheet pieces cut out as convex portions (total convex portion pieces) and area standard paper are each copied by a copying machine. Cut out the area standard paper from the copied area standard paper. Similarly, a portion of all the convex portions is cut out from the paper on which all the convex portions are copied. Then, the cut paper is precisely weighed to 0.1 mg. And the area of all the convex parts is calculated from the following formula.
[Area of all convex pieces (m ² )] = [mass of paper cut out of all convex pieces (g)] / [mass of paper cut out of standard area paper (g)] / 100
(4) The basis weight of the convex portion is calculated from the following formula.
[Basis weight of convex part (g / m ² )] = [Total mass of convex part (g)] / [Area of all convex part pieces (m ² )]
(5) The area (m ² ) of all the recessed pieces and the basis weight (g / m ² ) of the recessed parts are calculated in the same manner. However, when an opening is formed in the recess, the area of the opening is excluded as described above.

  When an opening is provided in the concave portion of the sheet 12, the relative area of the concave portion is reduced, and the liquid cosmetic composition impregnated and held in the sheet 12 is likely to be unevenly distributed in the convex portion. This is advantageous because it easily moves to the hair. When providing openings in the sheet 12, the openings may be dispersedly arranged in the form of dots in the convex part and the concave part, or may be unevenly arranged at specific positions in the surface of the sheet 12. . The shape of the opening may be an isotropic shape such as a circle or a regular polygon, or may be an anisotropic shape such as an ellipse. The opening may be provided so as to penetrate the entire region of the sheet 12 in the thickness direction, or the opening is not completely penetrated, and some of the constituent fibers of the sheet 12 exist in the opening. Then, a thin film portion or a low basis weight portion may be formed.

  As will be described later, the sheet-like hair cosmetic of the present invention sufficiently wipes the hair, and a sufficient amount of the liquid cosmetic composition penetrates into the hair, so that the hair and the hair float by the so-called water set effect. It is preferable that a large amount of the liquid cosmetic composition can be retained in order to suppress the hair and give the hair a unity. For example, the maximum water retention rate of the sheet 12 is 700% by mass or more, preferably 800% by mass or more, more preferably 900% by mass or more, and further preferably 1000% by mass or more. The upper limit is not particularly defined, but is preferably 2000% by mass or less, more preferably 1500% by mass or less, and further preferably 1300% by mass or less. The maximum water retention rate is measured in accordance with JIS L1913: 2010 “General Nonwoven Testing Method 6.9.2 Measurement Method of Water Retention Rate”. The maximum water content measured in this manner is multiplied by the sheet mass of the sheet 12 to calculate the maximum water content.

  FIG. 2 shows an example of a sheet 12 that is suitably used for the sheet-like hair cosmetic of the present embodiment. The sheet 12 has the above-described convex portions, concave portions, and apertures. The sheet 12 has a first surface 21a and a second surface 21b located on the opposite side of the first surface 21a. In the sheet 12, ridges 22 as convex portions and grooves 23 as concave portions are alternately formed at positions corresponding to each of both surfaces 21 a and 21 b. Here, “formed at positions corresponding to each other” means that the flange 22 and the groove 23 of the first surface 21a are disposed, and the flange 22 and the groove 23 of the second surface 21b are disposed. This means that the positions match each other. The flanges 22 and the grooves 23 of the both surfaces 21a and 21b extend in parallel to each other and extend in a direction intersecting with each of the pair of both sides 21c and 21d extending in parallel with the sheet 12.

As shown in FIG. 4A, the thicknesses of the flanges 22 on the first surface 21a side are substantially the same at any position in the extending direction. As shown in FIG. 3, each groove 23 on the first surface 21 a side is formed between the adjacent ridges 22 in the lateral direction. Here, there is no clear boundary between the flange 22 and the groove 23. However, when the boundary is clearly defined, for example, when the first surface 21a side is taken as an example, the height difference D _a (畝Position D _{a1 / 2} of ½ of the distance between the top of 22 and the bottom of the groove (excluding the portion where the opening 24 of the groove 23 described later is formed) The boundary is used (see FIG. 3). In addition, as shown in FIG. 3, in the cross-sectional view, each ridge 22 on the second surface 21 b side is lower than the ridge 22 on the first surface 21 a side, but has a contour that draws a downward convex curve. Each of the same-shaped and large-sized ridges 22 is arranged at substantially equal intervals in the lateral direction. As shown in FIG. 4 (a), each rib 22 on the second surface 21b side is in any position in the extending direction as shown in FIG. 4 (a). Is almost the same. Each groove 23 on the second surface 21b side is also formed between the adjacent ridges 22 in the lateral direction, similarly to the ridge 22 on the first surface 21a side. Therefore, the sheet 12 has a shape in which the thickness is periodically changed in the lateral direction in a cross-sectional view as shown in FIG. The thickness (height) of the flange 22 on each side of the first surface 21a and the second surface 21b is, for example, the above-described “height difference at the top of the flange 22”.

  Next, an example of a method for using the hair cosmetic product 10 of the present embodiment will be described. When the hair cosmetic product 10 shown in FIG. 1 is used, first, the opening / closing lid 11e attached to the upper surface 11b of the outer container 11 is peeled off from the upper surface 11b to expose the content outlet 11d. Next, as shown in FIG. 5, the sheet 12 accommodated in the outer container 11 is picked out with a finger through the exposed content outlet 11 d. By this take-out operation, the sheet-like hair cosmetic product 13 is squeezed at the end of the content take-out port 11d and easily spreads.

  Since the sheet-like hair cosmetic product 13 taken out from the outer container 11 has a low dampness and a high drape property as described above, it is placed on the inner side (palm side) of the hand so that it is placed on the finger. As shown in FIG. 6, it becomes familiar to the hand, and it becomes easy to perform the wiping operation of the hair and scalp. In particular, since the liquid cosmetic composition is impregnated and held in the sheet-like hair cosmetic 13 taken out from the outer container 11, it is likely to hang down by its own weight, and becomes more familiar to fingers.

  As shown in FIG. 6, when the sheet-like hair cosmetic 13 is spread and placed on the inner side of the hand so as to be applied to the finger, the state is maintained and the finger is applied to the root of the hair. For example, as shown in FIG. 7, a fingertip is placed at the root of the hair near the top of the head, and the sheet-shaped hair cosmetic 13 is brought into contact with the hair. Then, while maintaining the state in which the sheet-like hair cosmetic 13 is in contact with the hair, as shown in FIG. 8, the hand is moved from the base of the hair toward the hair tip to perform the hair processing operation. This operation can be performed on the entire hair, or can be performed on a portion of the hair. It is preferable to repeat this treatment operation for all the hairs. In order to be able to perform the processing operation on a clean surface at all times, it is preferable to perform the processing operation each time while changing the position of the sheet-like hair cosmetic 13 placed on the inside of the hand so as to be applied to the finger.

When the operation shown in FIGS. 7 and 8 is performed, the fingertip is applied to the base of the hair so that there is a hair bundle between the fingers of the hand on which the sheet-like hair cosmetic 13 is placed, and the state It is preferable to treat the hair while combing the hair down with each finger. For example, it is preferable to insert a finger into the base of the hair with the finger of the hand on which the sheet-like hair cosmetic 13 is placed slightly raised, and comb the hair with the finger in a state where the fingertip is indirectly in contact with the scalp. By performing such an operation, it is possible to treat the hair in a so-called “hand comb” sensation, and the treatment operation can be performed more easily.
In this treatment operation, the above-described operation can be performed by placing a fingertip in the middle of the hair, that is, between the root of the hair and the tip of the hair. From the viewpoint of uniformly applying to the entire hair, it is preferable to perform the treatment operation from the root of the hair bundle.

  In FIG. 8, the outer surface of the hair is wiped, but a palm is further placed on the inner surface of the hair (ie, the side closer to the scalp) and the sheet-like hair cosmetic 13 is placed between the fingers of the hand. It is also possible to apply a fingertip to the root of the hair or the middle of the hair so that a hair bundle exists in the hair, and wipe the hair while combing the hair with each finger under this condition. By applying the sheet-like hair cosmetic 13 to the hair by such a method, the liquid cosmetic composition can be uniformly and evenly applied even to hair that is usually difficult to apply to the hair and does not come out on the surface. Therefore, it is preferable.

  FIGS. 9A and 9B show another method of using the hair cosmetic product 10. In this method, as shown in FIG. 6 described above, the sheet-like hair cosmetic 13 is spread and placed on the inner side of the hand so as to be placed on the finger. Before or after this operation or simultaneously with this operation, as shown in FIG. 9 (a), a part of the hair is separated with the other hand to make a hair bundle. Then, the separated hair bundle is grasped with the hand on which the sheet-like hair cosmetic 13 is placed. The position for gripping the hair bundle is preferably a position close to the root of the hair bundle. And as shown in FIG.9 (b), a hand is moved toward the hair | bristle tip of a hair | bristle bundle, holding a hair | bristle bundle. Thus, the liquid cosmetic composition impregnated in the sheet 12-shaped hair cosmetic is effectively moved into the hair bundle by moving the sheet-shaped hair cosmetic 13 so as to slide from the root of the hair bundle toward the hair tip. To penetrate. This operation can be performed on the entire hair, or can be performed on a portion of the hair. This method of use is particularly effective when making a straight style.

  FIGS. 10A and 10B show still another method of using the hair cosmetic product 10. In this method, as shown in FIG. 6 described above, the sheet-like hair cosmetic 13 is spread and placed on the inner side of the hand so as to be placed on the finger. Before or after this operation or simultaneously with this operation, as shown in FIG. 10A, a part of the hair is separated with the other hand to make a hair bundle. It is preferable that the position of the hand holding the hair bundle is approximately in the middle or near the tip of the length of the hair bundle. And the tip and the site | part of the vicinity are wrapped with the hand of the state which mounted the sheet-like hair cosmetics 13 among the divided hair bundles. Then, as shown in FIG. 10 (b), the step of repeatedly holding and opening the hand while wrapping the hair bundle and combing the hair at the tip of the hair bundle and the vicinity thereof. As a result, the waved hair is waved. This operation is preferably performed a plurality of times while shifting the position of the separated hair bundle. This operation can be performed on the entire hair, or can be performed on a portion of the hair. Moreover, you may rub it from the root or middle part of the separated hair bundle to the tip part. This method of use is particularly effective when a wave (curl) hair made by comb hair or chemical treatment is made into a wave (curl) style.

  FIG. 11 shows a usage method different from the conventional usage method. In the method shown in the figure, the finger of the hand carrying the sheet-like hair cosmetic 13 is inserted into the hairline of the neck, and the fingertip is applied to the hairline indirectly through the sheet-like hair cosmetic 13 to contact the scalp. Let While maintaining this contact state, if the hand is reciprocated up and down or left and right, and the fingers are moved up and down or left and right, the scalp is rubbed up to remove the dirt on the scalp. Moreover, if the finger is inserted from the body side as it is, the hair is held between the inserted finger and the finger, and the hand is moved from the root of the hair toward the tip, the dirt on the hair on the inner surface can be removed. . It suffices that the fingertip is brought into contact with the hair through the sheet 12 and can be rubbed right and left. For example, the hair is divided, the scalp is exposed, and the finger is brought into contact with the exposed scalp through the sheet-like hair cosmetic 13. You can also rub left and right. From the viewpoint of efficiently and uniformly wiping, it is preferable to apply a finger with a sheet on the hairline.

  12 (a) to 12 (e) show a scalp wiping method different from FIG. In this method, first, the unfolded sheet-like hair cosmetic 13 shown in FIG. 12 (a) is folded in half as shown in FIG. 12 (b), and the folded sheet 12 is further folded in FIG. 12 (c). Fold it in half as shown in Fig. 4. Next, as shown in FIG. 12 (d), a finger is inserted into the folded sheet-shaped hair cosmetic 13 and the sheet-shaped hair cosmetic 13 is gripped by hand. Then, the hand holding the sheet-shaped hair cosmetic product 13 is brought into contact with the scalp, and the scalp is rubbed with the fingertip via the sheet-shaped hair cosmetic product 13 as shown in FIG. At this time, it is preferable to place the fingertip in the hair division because the fingertip can easily reach the scalp. In addition, the folding method of the sheet-like hair cosmetics 13 is not restricted to this.

When the wiping of the hair and scalp is completed by the above operation, the entire hair style may then be adjusted with a brush or hand as necessary.
Further, after wiping the hair and scalp by these operations, preferably a liquid cosmetic that is transferred to the hair or scalp by the sheet-like hair cosmetic 13 for 3 hours, more preferably 5 hours, and even more preferably 8 hours or more. It is preferred not to wash off the composition.

The small piece was cut into a convex portion and a concave portion, and the total weight (g) of the convex portion and the total weight (g) of the concave portion were each precisely weighed to 0.1 mg. Thereafter, all non-woven fabric pieces cut out as convex portions (hereinafter referred to as all convex portion pieces) were copy-printed, and then the copy paper of all convex portion pieces was cut out and weighed precisely to 0.1 mg. A separately prepared square mount (area standard) having a size of 10 cm × 10 cm was copied and printed in the same manner as all the convex pieces, and the area standard portion was cut out and precisely weighed to 0.1 mg. Thereby, the area of all the convex part pieces was computed by the following formula.
[Area of all convex pieces (m ² )] = [copy paper weight of all convex piece portions (g)] / [copy paper weight of standard area portion (g)] / 100
Finally, the basis weight of the convex portion was calculated by the following formula.
[Basis weight / convex part (g / m ² )] = [convex part total weight (g)] / [total convex part area (m ² )]
Similarly to the convex portion, the entire nonwoven fabric piece cut out as the concave portion (hereinafter referred to as the whole concave piece) is copied and printed, and then the copy paper of the whole concave portion is cut out and weighed to obtain the weight of the area standard. From the ratio, the area of all the concave portions was calculated, and the basis weight of the concave portions was calculated.
